The employee promotion system, which was originally used to lure staff, was repurposed as a solution to the labor shortage problem. Kana, who would normally have no chance of being hired, was promoted to a full-time employee.

One day, a chef fed up with her uttered a single phrase, causing Kana to experience humiliation unlike anything she had ever felt before... It was also the moment when non-regular employment literally became sexual employment.
